Answer:

Slope = - 4/5

Y-intercept = 3

Step-by-step explanation:

y = - 4/5x + 3 is written in slope-intercept form: y = mx + b where m = slope and b = y-intercept

Since they’re already placed in their right order, the slope stays as - 4/5 and the y-intercept is 3

The number p is 20 more than the number q . using algebra write the relationship between p and q .
Anarel [89]
From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.
